How it is calculated
Difference = agency cost − in-house specialist cost. How much cheaper, % = difference ÷ more expensive option × 100%. A positive difference means the in-house specialist costs less than the agency.
The comparison only accounts for direct money cost for a comparable workload — it doesn't assess differences in quality, response speed, access to expertise across disciplines (which an agency can offer through its team), or the risk tied to a single in-house specialist leaving.
The ad budget for promoting posts is deliberately left out of this comparison — it's usually the same regardless of who runs the social accounts, and adding it equally to both options wouldn't change the difference between them.
